Steve Vosloo of Usability Junction collected the following list of links on the return on investment ("ROI") for usability and posted them to the SIGIA-L a few weeks ago.

• ROI for usability
• Usability & ROI: A Collection of Links
• Usability Cost Savings Quotes
• Intranet report with stats from NNG. This one's not free.
• Return on Investment for Usability Projects. Another contribution from NNG. This one's probably also not free, and won't be available until August 2002.
